System for dissipating electrostatic charges

Abstract

The invention relates to a system for dissipating electrostatic charges (3) of a pluggable electrical unit (2) with an at least partially electrically conductive housing (20) when it is brought into connection with an at least partially electrically conductive enclosure (10) connected to earth potential of an electrical base unit (1) using a pair of leading contacts (131, 231). In this case, the enclosure (10) is connected to earth potential (4) of the base unit (1) via a first attenuator (111/121), to the frame potential (14) of the base unit (1) via a second attenuator (112/122) and to a first contact device (131). The frame potential (14) of the base unit (1) is connected to a second contact device (132). The housing (20) of the pluggable electrical unit (2) is connected to the frame potential (24) of the pluggable electrical unit (2) via a third attenuator (211/221) and to a first mating contact device (231) via a fourth attenuator (212). The frame potential (24) of the pluggable electrical unit (2) is connected to a second mating contact device (232). The first contact device (131) of the base unit (1) can be connected to the first mating contact device (231) of the pluggable electrical unit (2) and the second contact device (132) of the base unit (1) can be connected to the second mating contact device (232) of the pluggable electrical unit (2), the pair of leading contacts being formed by the first contact device (131) and the first mating contact device (231).
